Blanco was one of the first to engage in large-scale smuggling of cocaine into the United States from Colombia and set up many of the routes used by the Medellin cartel after she was sentenced in the United States in 1985, the BBC reported.

Investigators told the Herald that they estimate conservatively that Blanco was behind about 40 slayings. She was convicted in connection with three murders: Arranging the killing of two South Miami drug dealers who had not paid for a delivery, and ordering the assassination of a former enforcer for her organization, an operation that resulted in the death of the target’s 2-year-old son, the Herald reported.
